title: Order of genes on human chromosome 5q with respect to 5q interstitial deletions.
abstract: Using (a) somatic cell hybrids retaining partial chromosome 5 and (b) clinical samples from patients with acquired deletions of the long arm of chromosome 5, combined with chromosome 5-linked DNA probes, some of which exhibited RFLPs, we have determined the order of a series of genes on chromosome 5. The order established is 5pter----MLVI-2----cen----HEXB----DHFR----Pi227- --- cp12.6----(IL5,IL4)----IL3----GMCSF---- FGFA---- (CSF1R,PDGFR)----(treC,ADRBR)----(ARH-H9,CSF1 )----qter. The suggested order and orientation for the closely linked IL3/GMCSF gene pair is cen----5' IL3 3'----5' GMCSF 3'----qter, on the basis of analysis of the GMCSF rearrangement in HL60 DNA. The map position of the GRL locus, which was consistent with both somatic cell hybrid and 5q- analyses, was telomeric to GMCSF and centromeric to CSF1R/PDGFR, near FGFA. Long-range restriction-enzyme analysis of 5q- DNAs did not detect rearrangements of 5q-linked probes except in HL60 DNA, but it did reveal putative long-range RFLPs of several loci. RFLPs for GRL, Pi227, cp12.6, IL3, and CSF1R can detect deletions in bone marrow and in leukemia cells from patients with acquired 5q deletions.
